I have the blu studio 5.3. My carrier is straight talk. The internet worked perfect for about three weeks. Since then when i try to connect, i keep getting an error message stating "requested content cannot be accessed. Access is not allowed for this user agent".. The strange part is my twitter ap works fine, and i even listen to music on radio.com. It just wont allow me regular internet access. The folks at straight talk have had me re-enter my apn settings about a thousand times. Yet it still doesnt fix the problem. Somebody please help!!!!!!
